IMPROVEMENT IN HEEL-PLATES FOR BOOTS AND SHOES.

Specification formingpart of Letters Patent No. 131,452, dated September17, 1872; antedated September venteda new and useful Improvement inlite-- volving Heel-Plate for Boots and Shoes; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to make and use the same,reference being had to the accompanyin g drawin gformin g part of thisspecification.

This invention relates to a new and useful improvement in revolvingheel-plates for boots and shoes; and consists in the combination of afasteningscrew, conical washer, elastic disk, and revolving flangedmetallic plate, as hereinafter described.

In the accompanying drawing, Figure 1 rep resents the heel-plate asapplied to the boot, but showing it in vertical section. Fig. 2 is abottom view.

Similar letters of reference indicate corresponding parts.

A is a metallic plate, having a hole in its center and a dovetailflange, B, on its outer edge, as seen in Fig. 1. O is a disk, of rubberor other elastic material, of a diameter to fit within the flange B, andof sufficient thickness to project below the flange and form thewearing-surface of the heel. D is the fasteningscrew, which passesthrough the center of the rubber disk. E is a conical metallic washer orexpander, which is of a size and form to fit the under side of thescrew-head. As the screw is turned into the heel for fastening the platethe conical washer will be forced into the rubber disk, and force itsedge into the dovetail groove of the plate. This holds the edge of therubber securely to the metallic plate. The screw-head penetrates therubber disk so that the disk forms the wearing-surface of the heel.

It will be seen that the heel-plate, thus formed, will revolve on thescrew, the wearing-surfaces being metallic, as the conical washer E willbe fast or stationary in the disk. As the wearer turns upon his heel theplate will partially revolve and change its position, and the resultwill be the heel will wear square and the foot will consequently bethrown squarely upon the sole, thus greatly increasing the durability ofboth heel and sole. The rubber heel prevents slipping on the ice andadds to the elasticity and gracefulness of the step, while carpets arenot injured by projecting nails or sharp angles.

I am aware that a revolving heel with rubber wearing-surface is notnovel. I therefore disclaim such a heel; but I am not aware that aconical metallic expanding washer has been heretofore used.

Having thus described my invention, I claim as new and desire to Secureby Letters Patent The combination of the revolving flanged metallicplate A, rubber disk 0, conical expanding washer E, and fastening orpivot screw D, arranged substantially as specified.
